FaxModem/V.42bis  (250-3028)        Features           Faxback Doc. # 3287


This faxmodem is a Hayes and CCITT V.22bis/V.22 compatible auto-dial/auto-
answer modem that provides all the fallback and operation requirements for
asynchronous data communication at 2400, 1200, and 300 bps, and supports
all the current Hayes commands for asynchronous operation, including all
S Registers, AT Commands, and Dial Commands.  It also supports the V.27ter
and V.29ter fax protocols for sending and receiving fax at 9600, 7200,
4800, and 2400 bps, and can automatically sense and adjust to the speed of
a slower fax machine.  Settings and phone numbers can be saved to the
faxmodems non-volatile memory.

The faxmodem is also fully compliant with the international V.42bis
standard for data compression and error-correction, which encompasses V.42
automatic error-correction and MNP levels 1 through 5.  Each connection to
another modem is automatically negotiated to ensure that the highest
compatible level for data compression and error-correction is used.

Special features of the faxmodem include superior call progress tone
detection, a high-power micro speaker and amplifier with software volume
control for better call monitoring, adaptive equalization, and MOV
varistor lightning protection.

The faxmodem includes the full complement of 8 status lights PLUS
configurable status codes that appear on your computer monitor or terminal
screen.

Your faxmodem has the following features:

    - 2400/1200/300 bps Hayes compatible modem

    - 9600/7200/4800/2400 Group III Class 2 facsimile with
      hardware-based T.30 for superior background operation

    - Compatible with Hayes AT Commands and extended AT Commands,
      S Registers, and Dial Commands plus Extended AT Fax Command Set

    - Fully compliant with CCITT V.42bis and V.42 protocols

    - Supports MNP 1 through 5 and MNP Command Set

    - Supports the following data protocols:

        - CCITT V.22 bis (2400 bps international standard)

        - Bell 212A (1200 bps U.S. standard)

        - CCITT V.22 (1200 bps standard used in most countries
          outside the U.S.)

        - Bell 103J (300 bps U.S. standard)

        - CCITT V.27ter (4800/2400 bps fax standard)
